Specification of Letters Patent.

Patented Jan. 8,1907.

To all whom it mayoncern.- v

Be it known that I, THOMAS J. LINDSAY, a citizen of the United States, residing at Indianapolis, in the county of Marion and vState of Indiana, have invented certain new and useful Improvements in Steering-Spindles, of which the following isa specification.

The object of m invention isl to provide a two-part pivota support for a steeringwheel spindle, the construction being such that said two parts may be readily and conveniently machined and fittedfor attachment to the ends ofan axle structure formed preferably of an I-be'am, andthe construction also being such that said twopart support may be secured inposition with a minimum number of fastenings, the two parts of the support being preferably identical.

invention. l Figure lgis a side elevation ofl-an embodlment thereof; FigZ, a similar yiew with the The accompanying drawings illustrate my s indle-supports in vertical section; Fig. 3, a

p an of one of the spindle-supports Fig. 4, an end lelevation of the structure shown 1n Fig. -3 Fig. 5, a perspective view of the end of an I-beam axle formed to receive my improved spindle-support; Fig. o, a' perspective view of the completed structure, and F1' 7 a perspective view of one of the spind e-supportmembers. j'

n the drawings, 10 indicates the steeringwheel spindle provided at one end with a pair .of oppositely-eiitending 'ournals 11 1 1, which .are preferably integra with the spmdle structure, and each terminating in a polygonal portion 1v1 and a threa the length of the other in order that it may receive both of the arms 13l and 14, asshown .inFigs. 1 and 2, or said arms 'may beattached to the spindle structure at its opposite ends, as sliownin Fig. 6. A1collar 151s provided as a necessary filling-piece to be applied to the shorter polygonal portion 11 "vrtlienthe arms 13 and-14 are applied, as

shown'in Figs. lvvand 2, or applied to the .longer polygonal portion 11 when the arms 13 and 14 are assembled, as shown in Fig. 6; A nut 16 is provided for each of the threaded ends 11. IEach journal 1.1 is received in a y bearing 20, which is preferably provided with a bushing 21, having a headed inner end 21 for a purpose which will appear.

ticalvand are carried by identical structures,

l ed end 11.. One of the portions liis preferably double In the drawings the bearings 2()I are idento such an identical fstructure, will be readily `variations of proportions in the two parts without avoiding the s irit of my invention. Each bearin is carried at the up er outer corner of a ar 22, which is slitte ,longitipfand I shall therefore confine .my description i l although it understood that there'may be dinally, as at 23, and each bar 22 ispro;

vided in its inner edge with one or more` transverse grooves 23', the arrangementibe- A ing such that said transverse grooves of the two bars 22 will register to form bolt-openings, each adapted to receive a bolto'r other transverse fastening' member 24. The b ars 22 are'machined accurately along their inner edges 22and theirouter edges 22". When the structure is to be applied to an I-beam axleBO, the I-beam is suitably milled outvbetween its flanges 30 on each side, as at 31,

simple -to manufacture. "Qlhe member 20 22 will be made preferably as a drop-forging,

and the bearing 20 will be first fitted to receive the bushing 2,1. The art will then be jigged from this opening anc a milling-cutter run lengthwise through the arm 22 to formv the slit 23. At the same time, it desired, the 'inner edge 22 of the-arm 22 may be Jfaced. 'lwo members may then be clamped together upo their mating faces 22', and the inner ends of the arms 22 run between a pair oi4 so as to' form the' surfaces milling cutters, 22l and properly dimensionl the completed structure. A proper milling-cutter may be run between the flanges 30.

transversely between suitable milling-cutters to strip ofi the ends ofthe langes-30.- In order to assemble parts, the bushings 21 will first be introduced at the inner or adjacent ends oi the bearings 20 and ythe bearing structures 20 22 then placed upon the journals 11 of the spindle structure. The inner ends oi the arms 22 are then inserted between the overhanging anges of the ends of the I-beam 30, the projecting tongue 30 of the web passing into the slits 23er' the arms IIO.

22. The fastening-bolts 24 are then readily passed throughth'e registering openings -23 and 32. By this arrangement all of the parts are held into position by the fastenersl 24, and the bushings 2l are automatically held in position by the steering-spindle structure` The I-bearn 3() may readily be of standard form, and it will be seen thatitrnay be bent into any desired form, the steering-spindle supports bein-g readily attached to its ends ater'ithas been bent 'to desired shape.`
